Resumen

Time partitioning is an understudied mechanism for frugivorous bat species that coexist in competition. We describe activity patterns of Carollia perspicillata (Linnaeus, 1758), Carollia brevicauda (Schinz, 1821), and Carollia benkeithi Solari & Baker, 2006 using time of capture variation in a premontane forest of central Peru. For C. perspicillata, activity patterns of different sexes and seasons (rainy vs. dry) were also compared. We report temporal coincidence (∆=0.91) among the three species being more active at the beginning of the night when resources are available. Neither sex nor season changed the activity pattern of C. perspicillata. Evidence suggests that these sympatric species do not reduce competition through time partitioning.
